Abstract
A blowout preventer (BOP) health monitoring system includes a controller having a tangible, machine readable-medium storing one or more instructions executable by a processor. The one or more instructions are configured to receive feedback from a sensor, where the feedback is indicative of a pressure within a BOP stack over time, determine a position of a plurality of components of the BOP stack, determine a start point and an end point of a pressure test based on the feedback, determine a decay and a hold duration of the pressure test based on the feedback, the start point, and the end point, determine a health index of the BOP stack based on the decay and the hold duration, and provide an output indicative of a condition of the BOP stack based on the health index.
